Check if remote folder exists

Hi,

When trying to chk if a folder exists on remote server using the below command (got it from other thread in this forum)

"if[-n `ssh vchr@s1.mrix.local '/cygdrive/d/shares/projects\ data\ load/test\ files/$SCPED_FILES$name$code'`]; 
then
     echo "Directory exists";
else
     echo "Directory not available";
fi"

I get error " syntax error: `then' unexpected". Please help....

Thanks
